MIG WELDING CARBON STEEL UPHILL 1/4" THICK OUTSIDE CORNER

Mig welding uphill with c25 gas requires lower settings that shown on a mig settings chart. Especially on an outside corner joint.

Downhill is easy. But you risk lack of fusion on anything thicker than 1/8".

So it pays to be able to mig weld uphill.
